Abstract

BACKGROUND: Various techniques exist to decrease the false negative rate (FNR) of axillary surgical staging post neoadjuvant chemotherapy (NAC). While biopsy-proven positive lymph nodes (LNs) are often clipped prior to NAC, the value of clipped node localization is debated. METHODS: We identified cT0-4c biopsy-proven cN+ breast cancer patients with a clipped LN treated with NAC and definitive surgery (September 2016-July 2024). The axillary staging procedure included sentinel lymph node (SLN) surgery or targeted axillary dissection (TAD). Frequency of the clipped node being an SLN and FNR of the clipped node versus all nodes removed during SLN surgery/TAD were determined. RESULTS: Of 540 patients with 541 cN+ breasts with cancer, 456 patients had a positive LN clipped prior to NAC and underwent axillary surgical staging (404 TAD, 52 SLN surgery). The clipped node was retrieved in 93% of eligible patients (96% TAD vs. 77% SLN surgery; p < 0.001) and, if retrieved, was an SLN in 86% (85% TAD vs. 92.5% SLN surgery; p = 0.20). The median number of nodes retrieved was four for both SLN surgery and TAD. Among 204 patients with ypN+ disease who had the clipped node and additional non-clipped nodes removed, FNR of the clipped node was 5.4%, and FNR of the SLNs was 4.9%. CONCLUSION: In a contemporary NAC cohort of cN+ patients, the clipped node was retrieved and was a SLN in most cases. When compared with all nodes removed during SLN surgery/TAD, the clipped node FNR was low, thus supporting the potential for limitation of axillary staging surgery to selective removal of the clipped node alone.

摘要

背景:存在多种技术可降低新辅助化疗(NAC)后腋窝手术分期的假阴性率(FNR)。虽然活检证实为阳性的淋巴结(LNs)在NAC前常被夹闭,但夹闭淋巴结定位的价值存在争议。 方法:我们纳入了2016年9月至2024年7月期间接受NAC和根治性手术治疗的cT0-4c活检证实为cN+且有夹闭淋巴结的乳腺癌患者。腋窝分期程序包括前哨淋巴结(SLN)手术或靶向腋窝清扫(TAD)。确定夹闭淋巴结为SLN的频率以及夹闭淋巴结与SLN手术/TAD期间切除的所有淋巴结相比的FNR。 结果:在540例患有541个cN+乳腺癌乳房的患者中,456例患者在NAC前有一个阳性淋巴结被夹闭并接受了腋窝手术分期(404例TAD,52例SLN手术)。93%的符合条件患者的夹闭淋巴结被找回(TAD为96%,SLN手术为77%;p<0.001),如果被找回,86%为SLN(TAD为85%,SLN手术为92.5%;p=0.20)。SLN手术和TAD找回的淋巴结中位数均为4个。在204例ypN+疾病且夹闭淋巴结和额外未夹闭淋巴结被切除的患者中,夹闭淋巴结的FNR为5.4%,SLN的FNR为4.9%。 结论:在当代cN+患者的NAC队列中,夹闭淋巴结大多被找回且为SLN。与SLN手术/TAD期间切除的所有淋巴结相比,夹闭淋巴结的FNR较低,因此支持仅选择性切除夹闭淋巴结来限制腋窝分期手术的可能性。
